Another object orn the inventionis to providein mechanism of the aforementioned nature an adjustable stop through which the maximum elevation of the wick may be l varied.

vention is to provide a unique connection j between the flame spreader and stop mechanism which renders the removal and replacement oi thespreader particularly easy; the connection automatically7 assuming effective condition when the spreader is inserted within the upper end ot the wick tubes.

Embodiments serving to illustrate `the invention are shown in the accompanying drawings and while l shall proceed to describe them in detail, it will be understood that l do not limit myself to the structural features thereotl further than is required by Y the terms of the claims annexed hereto.

In the drawings, Fig. 1 is a sectional side elevation of a burnerv incorporating myy improvements; the plane of section being parallel to the axis of the wick raising` spindle; Fig. 2 is a horizontal section through the burner on the line 2--2 of Fig. 1; Fig. 3 shows the burner in sectional side elevation, at right angles to the plane of Fig. 1; the wick being down andthe wickstop mechanism in ineii'ective condition; Fig. 4 is a similar view showing the wick partially elevated and certain parts movable with the wick in what may be termed intermediate position; Fig. 5 is a view, similar to Figs. 3 and 4, and showing the wick at .its maximum high position and the stop mechanism in effective condition; Fig. 6 (Sheet 3) is a fragmentary perspective view ot a baeket which depends from the burner and whereby certain parts of the stop mechanism are guided; Fig. 7 (Sheet 11) isa similar view of a frame which constitutes part 'ot the stop mechanism; Fig. 8 (heet 2) is a perspective view ot the pawl and stop carrying member of the stop mechanism; Fig. 9 is sectional side elevation of a burner incorpo rating. a modified form of my invention; Fig. 10 is a section on the'line 10-10 ot Fig. 9; Fig. 11 is a sectional view through' the burner at right angles to Fig. 9; Fi 12 and 13 are fragmentary sectional views corA responding in their plan ot section with that .supported by a wick carrier 7. wick tube 1 has an offset 10 which extends' oit Fig. 11 but showing the stop mechanism in intermediate position and in effective con dition; respectively; Fig. 14 is a fragmentary perspective view orp a bracket employed in the later form of my invention; Fig. 15 is a similar view ot' the slide; Fig. 16 is a perspective view of the weighted pawl and stop; Fig. 17 is a sectional detail showing a construction that distinguishes from the pre vious terms by employing` a pivoted pawl:l and Fig. 1S is a perspective view showing the pawl carrying member and the pawl pivoted thereto.

The burner illustrated in Figs. 1 to 5 com prises inner and outer wick tubes 1 and 2 that are joined together at lower ends by a wall 3 so as to enclose an annular wick space or compartment wherein tubular wick '5 is rlie inner radially inward and is closed at the bottom by a wall 11 and at the top by a wall 12. the latter having a tubular extension 13 through which a rod 15 extends that has connection at its lower end, through a member 1G. with the wick carrier 7. rThe upper end or" the rod 15; where it projects beyond the tubular extension 13, has connection at 17 with a rack member 18. This member is preferably formed ot sheet metal and extends a considerable distance below the burner tubes where'it is U-shaped in cross sectionj while thereabove and throughout the remainder ot its Vlength its curved side is cut awaj.y leaving only side plates that are turned inwardly and overlapped at their upper ends tor conneetion with the rod 15 aforesaid. The nearer side of the lower portion ot' the memf ber 18 (as it is viewed in Figs. 1 and 2) is provided with a series et slots 20. thus constituting of it a rack 'tor engagen'ient with the teeth of a pinion 21 on a spindle 22 which. may be turned b v a hand wheel 23 applied to its outer end. The spindle is jonrnaled withiu opposed parte ot a brarket 5 that is secured to and depends trom the burner.

It maybe explained in passing that. in the present construction. the burner is intended to be supported troni the base ot a stove through a member 2G that is applied to the 'forward end of the bracket 2f and which is arranged to have connection with the base, and through an elbow itting 2T that extends rearwardly trom the lower end oi" the outer wick tube 2 and is arranged tor connection with asuitable supply pipe. thc ntting 2T providing communicative conn eetion between the supply7 pipe and burner.

lt will be seen L'oirV what has already been described that by turning the spindle 22 the wick 5 may be raised and lowered b v reason ot' its operative c'onnections'with Ythe spindle through the carrier 7. member 16. rod 15; rack member 18. and pinion 21.

tongue which is turned laterally so as to but the edge of the aforesaid haine. This stop is preferably adjustable (in the present instance, by reason ofthe flexibility of the metal whereof it is formed) so as to enable the high position of the wick to be varied to meet varying climatic conditions and `difierent zQjrades of fuel oil, etc., some oils requiring greater wick exposure than others as does also varying atmospheric or climatic conditions.

i have already made mention ci the tact that the pawl 39 is yieldable. This is for the purpose ot avoiding the pawl locking,` with a gear tooth should the nose the pawl engage squarely on the point ot the tooth.

llVhile l have described inpassing" the operation et the various parts, l may eX- plain briefly that when the burner is in use and the user wishes to clean the wick, or replace a consumed wick by a new one, the flame spreader is removed by ,lifting it through the medium ot tie collar or actuator 55, which, as previously explained, auto matically unlatches the flame spreader from the post l,Vith the flame spreader re moved, the wick has clear upward course. The spindle 22 is turned to the ripght (as the parts are herein illustrated) and, in the absence oi' the llame spreader. there being' nothing' to litt the frame 31, the wier: stop mechanism will not be thrown into operative condition so that the wick may be raised until its iipper end protr-` c es enough above the tubes for cleaning purposes, or until the carrier 7 is exposed suiiiciently above the upper ond ol the wick tubes to allow the same to be lifted therefrom. A new wick, equipped with its own carrier, may now be inserted between the tubes and pressed down until it engages the member 16 and until holding' prongs, indicated in a general way at y7() in 2, take bold ot the upper edge of the carrier` the toothed upper edges ot said prongs being indicated in said view in dotted lines. This' Jfeature will constitute the subject matter ot a divisional application and turt ier illustration ot' it in this connection trbt toibo unnecessary. `With the wick' now locked to the member 16, the spindle 22 may be rotated in a direction to retract the wick and sutli cicntly to draw itcomplctelv into the wick spaceW t1 The flame spraderis ylinen lowered. into the upper end oic the burner over the post and is automatically latched thereto by the swinging' of the latch plate i7 to normal position under the action ot its weighted end he burner is now in readiness tor use. When it is desired to light. the wick` the wick is elevated by turninpthe spindle Q2 in an appropriate direction and upon theinitial upward movement imparted to the dame Aspreader by the engagement of the wick Vwith its flange 58 the franiell and the pawl carrying member 85 will be elevated sutliciently to present the nose of the pawl in the path of the teeth ot' ratchet 60 whereupon the ratchet picks up the pawl and through it, and the member 35, frame 31 and Spanner 30, lifts the ilame spreader 50 out oi contact with the wick, this action continuing` until the lower edge of the pawl carrying` member escapes over the upper end ot wall 62, thereafter leaving the flame spreader at rest while allowing the wick to continue upwards until the parts are arrested in their movement by the engagement of stop with the adjacent edge ot the frame 31.

The embodiment illustrated in 9 to 1.6 is quite similar to that above described, and with an understanding ot the previousr torni, the construction and operation oit the present modification will be readily comprehendod from the 'following' bric'i' description.

The burner is made up of inner and outer wick tubes T5 and 7 6, respectively, that are joined at their lower ends by an annular wall 77 thereby to enclose a space 76 which contains the tubular wick 79 equipped with t carrier 80. Walls 81, spa-ced a suitable distance apart,

extend diametrically across the inner wick tube and the space therebetween is closed at the lo 'er end by a wall 62, and at the upper end by a wall S?, which has a tubular extension through which a rod projects, the rod having attached to its lower end a cross bar 85al which is adapted to have separable con- L-ection through suitable means (not shown) with the wick carrier 80. At its upper end, the rod 85 has connection with a rack member 86 that depends along one side or" one of the walls S1 and aperture 87 in the horizontal portion 86 of a. bracket S9 which is attached to the lower end of the burner. ylhc wick raising spindle 90. equipped at its outer end with a hand wheel 91. is iournaled in opposed parts 92 and or the bracket 89, and has secured to it a` pinion 95 (shown double, in the present instance) which meshes with apertures 96 in'the rack member 86 so that when the spindle is rotated it will through the rack member 66, rod 85, and cross bar 85, raise and lower the wick.

A Spanner 100 is suported tor vertical movement: within the upper end of the inner uuid-ed through an wick tube 75, and atta-#hed thereto is a frame t nection with the wick raising means, a flame spreader arranged to be engaged and moved byI the wick when the latter is elevated,
